I am a førsteamenuensis (UK: lecturer, US: assistant/associate professor) in the Department of Mathematics at the Norwegian University for Science and Technology. I work in both differential and algebraic topology, both of which require that I use some category theory from time to time. I am also extremely interested in how best to use technology to help us do mathematics, particularly in the purer ends of mathematics where the obvious computational uses are not so useful.

comment Dashed lines only for covered boundaries with TQFT
There's a node shape tqft boundary circle which you can use rather than the cap. Your middle node would be \node[tqft boundary circle,draw] at (A.outgoing boundary 1) {};. The ability to style incoming and outgoing boundary components differently is on the TODO list for this package.

@Tarass I recommend that you accept Claudio's answer. It's the better solution.

comment Tikz shortandoff-on newcommand problem
@ClaudioFiandrino I was completely unaware of the existence of this library! (And it doesn't appear in the documentation as far as I can tell.) What it appears to do is to effectively issue \shorthandoff at the start of the tikzpicture and \shorthandon at the end, plus some extra for handling nodes. That's neat. I recommend you post that as a solution.

comment Tikz shortandoff-on newcommand problem
@ClaudioFiandrino Not sure I get what you're suggesting there. The problem isn't (I think) with the order of loading. babel doesn't do its catcode changes until the \begin{document} is issued, so any commands defined beforehand are in the old catcode regime not the new one.

comment Tikz shortandoff-on newcommand problem
@percusse \show\pgfversion reports 3.0.0 on my system and I saw the problem with the original code. So whilst TikZ v3.00 probably is better than previous versions, it doesn't appear to have a complete solution. Not that I think it should: a complete solution would be to test for every catcode variant of the given character each time which would be far too expensive.
